In the busy world of civilization the truths of science seem to leave little impression. We have so much else to think of, so much beside to occupy our attention, that they excite only a momentary feeling of wonder, and we are inclined to think that, after all, it is a matter of small consequence what lies beyond our little world. But when we have been for months cut off from civilization, when there are none of the distractions of daily life to arrest our attention, then, in the midst of the desert, or deep in the heart of the mountains, these truths approach realities. Then it is that we think over the facts which the science of astronomy presents. The distance of the stars, so great in certain cases that the light from them, travelling at the rate of one hundred and eighty-six thousand miles in every second, must have started before the birth of Christ to reach the earth in our day ; and their numbers, which are reckoned not by thousands, but by hundreds of millions, will furnish instances of the truths to which I allude.
Such, we are tqld, are the distances and number of the stars ; and their size, and the speed at which they are travelling, are equally marvellous. But what is beyond them ? Say we could travel to the very furthest star that is to be seen from the earth, what is beyond that ? Is that star the limit of everything ? is there yet another hundred million stars beyond ? Then, again, when we learn that all this world, and the sun and the stars, came from a vast expanse of nebulous gas, where did that gas come from ? And what will happen to all these myriads of worlds ? It is said that the earth will become cold, barren, and lifeless as the moon, and then be drawn into the sun, which itself will have expended the last ray of heat it has been giving out for millions of years, and will go whirling through space,
a cold, dead, lifeless star. Is every star to burn itself out like
